TO ALL PERSONS TO WEQM THESE PRESENTS MAY COME:

Be it known that I, LUTHB. H. FAnNswoRT-H, of Hudson, in the conntylof Middlesex, and State'of Massachnsetts, have invented an Improved Awl-Haft; and I de hereby declare the same to be fully describediin the following specification, and represented in the accompanying dra-wings, of which-1 Figure 1'is a front elevation,

Figure 2 a top view, and Y Figure 3 a. longitudinal section of it.

Figure -4 is a side view, and' Figure 5 a. top view of the hinged jaws,'with their conical screw.

In such drawings, A A are two jaws, having their shanks made conical, and provided with a screw, cut on theni, as shown at a a. The two jaws are also to be so formed that they may be embraced or grasped by a wrench and revolved thereby.Y The shanks of the jaws are to behinged together by a.pin,'b, going through bothof them, near their-lower ends. Each jaw, at the. middle of its inner face, is to be grooved lengthwise, to receive the shank o f an awl.' These grooves are shown at cve in iig. 5, one of them also being shown at c in, lig. 6, which is an inner side view of'one of thejaws. l

The conical shanks -of the jawsare to screw into a conical socket, d, formed in a round'head,B, the socket being provided with a fenialc screw'to receive the screw of tlie two shanks.

A screw, C, is extended from the said socket Bin p n1 anner as represented in the drawings, and on this screw, leather disks, D.D, are to be placed, and'screwed until they may come close together, cement orIv glue being usedto connect the surfaces of such disks`I -The end of the screw, 'and that of the last diskV screwed thereon, are to be covered by a disk, D', connected to it, or by another set of disks, D, connected together, and a cemented to snch ends, thesame being as rappresented` On placing an awl in the grooves of the jaws, and revolving the jaws, they will screw into the socket d, and by it will be contracted or made .to approach one another, so as toiirmly grasp and hold the awl.fr

When the handle is formed part as explained, of disks or sheets of leather, or its equivalent, screwed I npon a screw, as set forth, itbec'omes very strong, and is not liable to split under the blows of n. hammer while Y the awl is being driven into asole. ,p l p I am aware that jaws to fit to a conicalsocket, and provided with long and connected Shanks, and a screw and nut at the ends of the Shanks, to 'draw the'jaws into'the sockets, have been applied to'a handle, the whole Y constituting an awl-haft, which the socket-'has been at one end,r and the screw and nut at the other end of the haft. Y l,

I am also aware that spring-jnws, inode conical, and provided with a male screw on the cone, and with :o nut to screw on thesaid screw, have been fixed into a handle, to constitute therewith an awl-haft.

I n'iake no claim to either of such constructions, combinations,'or arrangement of parts.

I claim the vjaws A A, as made Vwith the.conical and screwed Shanks,` and the socket-headRas in ade with a conical'month and a. screw arranged therein to receivethe screwed shanksotv the jaws, the whole being substantially usand tooperate as specied. f Y

I also claim the combination of the screw C with the `head B, and the series 'oi' disks D D", of-leathcr or other proper material, screwed on such screw, as described. I

I also claim the" arrangement of the -conneetion-rivet oi pin b, viz, within the conical Shanks, and transversely through their screw, and with respect to the jawsA A as represented.V i
